一、前言随着我国社会主义建设事业的蓬勃发展,桩基工程日益增多。以往确定单桩承载力的多种方法之中,比较可靠的是采用单桩静荷载试验(试桩),但是,试桩不仅费时、费力、费钱,并由于设备及其它原因,不能在设计施工之前取得资料,因此,往往失掉了指导设计施工的作用,给工程造成一定的损失。近几年来,静力触探在我国迅速发展,在浅基础承载力方面,武汉、天津等地区已作了大量的对比试验和分析,获得一定的成果,至于静力触探在确定单桩承载力方面的应用,虽然在天津、北京、南京、上海等地区作了一些试验分析,但仍处于摸索阶段。为了探索静力 I. INTRODUCTION With the vigorous development of China’s socialist construction, pile foundation projects are increasing. Among the various methods for determining the bearing capacity of single piles in the past, it is more reliable to use the single pile static load test (test piles). However, the test piles are not only time consuming, laborious and expensive, but also cannot be designed due to equipment and other reasons. Before the construction, the data was obtained. Therefore, the effect of guiding the design and construction was often lost, causing some loss to the project. In recent years, static cone penetration has developed rapidly in China. In terms of bearing capacity of shallow foundations, a number of comparative tests and analyses have been conducted in Wuhan, Tianjin and other regions, and certain results have been obtained. As for static penetration testing, the determination of single pile loading Although the application of force, in Tianjin, Beijing, Nanjing, Shanghai and other regions made some experimental analysis, but still in the stage of exploration. To explore static
